How is renal medullary carcinoma (RMC) defined? Expert Dr. Nizar Tannir explains RMC, who is most often impacted, and the risk factors for developing RMC.

[ACT]IVATION TIP
“for individuals who have sickle cell trait, first is to not panic, please. Sickle cell trait is very common as we know, at least 3 million in the United States have that. Vast majority of patients will not develop RMC. So people with sickle cell trait should not panic that they will…they are destined to develop RMC, because only very, very few will develop it.”

What exactly is renal medullary carcinoma? And is this disease exclusive to those with sickle cell trait?
Dr. Tannir:
Renal medullary carcinoma is the most aggressive type of kidney cancer and it afflicts young people who are African American in the United States, and the vast majority of these patients or these individuals, have sickle cell trait. But the reason the vast, and I would say 95 percent of subjects or patients who have RMC have sickle cell trait, is because sickle cell trait is much, much more common than sickle cell disease. And so statistically-speaking, sickle cell trait is much more common than we see, the vast majority of patients with RMC have sickle cell trait. So sickle cell trait…but in general, a broader sickle cell hemoglobinopathy is the most important risk factor for developing RMC. That’s the link, the most important link between the renal medullary carcinoma. That most aggressive kidney cancer type and sickle cell hemoglobinopathy.
There is a close type of kidney cancer where individuals will have similar tumor type. Aggressive, but they don’t have the sickle cell trait or other sickle cell hemoglobinopathies and that entity is called renal cell carcinoma, unclassified with medullary phenotype. Medullary phenotype is the resemblance with the RMC. My activation tip for individuals who have sickle cell trait, first is to not panic, please. Sickle cell trait is very common as we know, at least 3 million in the United States have that. Vast majority of patients will not develop RMC. So people with sickle cell trait should not panic that they will…they are destined to develop RMC, because only very, very few will develop it. So, I think it’s important to be aware of that link of RMC and sickle cell trait but not to really make it, and worry every day that this is…that they’re doomed.
I want people to really not panic and understand the link and have the awareness, and if they haven’t been tested for sickle cell trait, they should be tested. And I think nowadays all hospitals test the newborns for sickle cell trait, but it should not be a scare for people who have it already.
